D.is wrong

The answer is A. The brain tends to react to the excessive dopamine levels produced by the addictive substance, and therefore increases the amount of receptors in the brain that takes in dopamine. This is the best answer since there is a big effect when it comes to the brain and how it reacts to the emotion when we get high from a drug.

Lunar phases occur when the Moon appears to change shape as seen from Earth. What causes different phases of the Moon? Select one:
a. the tilt of the axis of Earth
b. the shadow of Earth falls on the Moon
c. the alignment of the Sun, Moon, and Earth in a straight line
d. the amount of the sunlit side of the Moon that faces Earth

Answers

Lunar phases are visible according to the amount of sunlit side of the moon facing the earth. So the correct option is D.

Why are lunar phases formed?

The moon does not produce any light of its own and only reflects the light falling on it from the sun. The sunlight hits all the sides of the moon but we can only see it when it falls on the side, or the part of the side visible to us.

So, when sunlight hits the far side of the moon, it is called a new moon. The far side is the side of the moon not visible from earth. Therefore we are unable to see the moon when this happens.

But when sunlight falls and reflects from the near side of the moon, a bright round structure of the moon is visible from the earth. This is called full moon.

Other than that there is the waning crescent, waxing crescent, first quarter, waxing gibbous, waning gibbous and third quarter. All these depend on the side of the moon visible from the earth when sunlight falls on it.

When, during the course of the revolution, the earth comes between the sun and moon blocking sunlight on the moon, a lunar eclipse occurs.

Therefore, the correct option is D.
